Published Study shows replanting logged forests with diverse mixtures of seedlings accelerates restoration
(via sciencedaily.com) • Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.
Published Clever lapwings use cover to hide in plain sight
(via sciencedaily.com) Original source Ground-nesting birds called lapwings use the shape of their nests and surroundings to hide from predators, new research shows.
Published Polar experiments reveal seasonal cycle in Antarctic sea ice algae
(via sciencedaily.com) Results provide the first measurements of how sea-ice algae and other single-celled life adjust to the dramatic seasonal rhythms in the Southern Ocean. The results provide clues to what might happen as this ecosystem shifts under climate change.
Published Rivers are rapidly warming, losing oxygen; aquatic life at risk
(via sciencedaily.com) Original source Rivers are warming and losing oxygen faster than oceans, according to a new article. The study shows that of nearly 800 rivers, warming occurred in 87% and oxygen loss occurred in 70%.
Published Scientists find good places to grow long-spined sea urchins, a starting point to restore 'the lawn mowers of the reefs'
(via sciencedaily.com) Scientists are trying to raise as many urchins as possible because they eat algae that could otherwise smother reef ecosystems and kill corals. Researchers have identified algae on which larval sea urchins grow into juveniles in a lab setting.
Published Protected nature reserves alone are insufficient for reversing biodiversity loss
(via sciencedaily.com) Original source Protected nature areas are considered fundamental for maintaining biodiversity and countering its loss. But how effectively do established protected areas work and prevent negative trends? Research shows mixed effects of protected areas on various species.
Published More Texas owls are testing positive for rat poisons
(via sciencedaily.com) New research suggests that owls in Texas have high rates of anticoagulant rodenticides (AR) -- blood thinning rat poisons -- in their systems.
Published New research reveals why and when the Sahara Desert was green
(via sciencedaily.com) Original source A pioneering study has shed new light on North African humid periods that have occurred over the past 800,000 years and explains why the Sahara Desert was periodically green.
Published Freshwater connectivity can transport environmental DNA through the landscape
(via sciencedaily.com) A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.
Published Nature's great survivors: Flowering plants survived the mass extinction that killed the dinosaurs
(via sciencedaily.com) Original source A new study by researchers from the University of Bath (UK) and Universidad Nacional Autónoma de México (Mexico) shows that flowering plants escaped relatively unscathed from the mass extinction that killed the dinosaurs 66 million years ago. Whilst they suffered some species loss, the devastating event helped flowering plants become the dominant type of plant today.
Published Plant-based food alternatives could support a shift to global sustainability
(via sciencedaily.com) Replacing 50% of meat and milk products with plant-based alternatives by 2050 can reduce agriculture and land use related greenhouse gas (GHG) emissions by 31% and halt the degradation of forest and natural land, according to new research.
Published Ecology and artificial intelligence: Stronger together
(via sciencedaily.com) Many of today's artificial intelligence systems loosely mimic the human brain. In a new paper, researchers suggest that another branch of biology -- ecology -- could inspire a whole new generation of AI to be more powerful, resilient, and socially responsible. The paper argues for a synergy between AI and ecology that could both strengthen AI and help to solve complex global challenges, such as disease outbreaks, loss of biodiversity, and climate change impacts.
Published Art, science merge in study of 19th-century landscape paintings' ecological integrity
(via sciencedaily.com) A collaboration of ecologists and art historians has demonstrated that landscape paintings from more than 150 years ago can advance environmental science.
Published Conservation in shark sanctuaries
(via sciencedaily.com) Original source Researchers are assessing the efficacy of shark sanctuaries by developing a modeling system that utilizes publicly accessible fishing data to determine shark catch and mortality rates. Their findings represent an important step in utilizing data science to tackle oceanic conservation challenges.
Published Lions on the brink -- New analysis reveals the differing threats to African lion populations
(via sciencedaily.com) Original source New results reveal that many of Africa's remaining lions live within small, fragmented populations at risk of disappearing. The researchers developed a new framework which integrates ecological and socio-political risk factors to better understand the fragility of these populations.
Published Scientists find evidence of sea star species hybridization
(via sciencedaily.com) A new study presents genomic evidence of hybridization between two closely related species of sea stars -- Asterias rubens, the common starfish, and Asterias forbesi, known as Forbes' sea star.
Published Bees struggle to find flowers because of air pollution
(via sciencedaily.com) Original source A new study has found that air pollution is preventing pollinators finding flowers because it degrades the scent.
Published Artificial intelligence could help build pollen jigsaw of present and ancient flora
(via sciencedaily.com) Original source An emerging system which combines rapid imaging with artificial intelligence could help scientists build a comprehensive picture of present and historic environmental change -- by swiftly and accurately analyzing pollen.
Published Invasive alien species play key role in 60% of global plant and animal extinctions
(via sciencedaily.com) A new report presents major findings on the gravity of impacts from invasive alien species on our planet.
Published Lack of evidence hampers progress on corporate-led ecosystem restoration
(via sciencedaily.com) An international team of scientists analysed publicly available sustainability reports released by 100 of the world's largest companies and found that around two-thirds of these global corporations are undertaking ecosystem restoration. However, the results highlight that despite many businesses claiming to actively rebuild damaged ecosystems, we know very little about what is actually being achieved.
